Hello, this is Administrative Scrivener Jean.
In 2003, a company acquired a food manufacturing and processing business that produced and sold products such as soybean paste.
The company also completed the filing for succession to operator status with the competent local authority.
At first glance, there seemed to be no particular problem.
The company had acquired an existing business and completed the administrative succession filing, so it would be natural to assume that the existing premises could simply continue to be used.
But approximately 18 years later, in 2021, a local government inspection uncovered a problem.
At the time of the original operating permit, the approved floor area of the main building was 587.4㎡.
In reality, the business was using 748.8㎡.
In addition, the business was using an unauthorized building behind the main building, from the basement level through the third floor, for food manufacturing and processing activities.
The local authority issued a corrective order because the business had changed the operating area without completing the required change filing.
The operator corrected the unauthorized expansion within the main building but did not resolve the use of the unauthorized building.
The authority eventually imposed a seven-day business suspension.
This was the case decided in Supreme Court Decision 2023Du57142, May 9, 2024.
The Supreme Court’s conclusion was clear.
A person who acquires a business where required changes to the business premises have not been properly reported may still be subject to corrective orders or business suspension if the person continues operating without completing the required filing.
The key lesson for anyone acquiring a store or business is simple.
The fact that succession to operator status is possible does not mean that the premises and facilities you are acquiring are themselves fully compliant.
When acquiring a business, you should not ask only:
“Can I legally acquire the business from this seller?”
You should also ask:
“Can I take over these premises in their current condition and continue operating the same business?”
That is the purpose of regulatory due diligence before a business acquisition.
“The Previous Owner Has Always Operated This Way” Is Not Proof of Compliance
When acquiring an existing business, buyers often hear statements such as:
“The previous owner operated this way for more than ten years.”
“The district office has never raised an issue.”
“We have always used that storage area.”
“There was no problem when I acquired the business either.”
But these statements are not enough to establish regulatory compliance.
The relevant question is not how long the previous owner operated the business.
The real question is:
Does the actual business operation match what has been permitted, registered, or reported to the competent authority?
Long-term use does not automatically convert an unreported area into a properly reported business space.
Likewise, the absence of an inspection does not make a non-compliant condition lawful.
In Supreme Court Decision 2023Du57142, the transferee had completed the succession filing in 2003 and continued operating for many years.
Nevertheless, the portions of the premises outside the reported business area remained a separate regulatory issue.
The Supreme Court specifically held that the acceptance of the succession filing for the main building did not give the transferee the legal right to operate in the unauthorized building that was not included in the filing.
So before acquiring a business, it is not enough to ask:
“Can the operator status be succeeded to?”
You need to go one step further.
“Exactly which spaces, in what condition, and with which facilities can legally be used for the business?”
Why Was There a Problem Even After the Succession Filing Was Completed?
Looking more closely at Supreme Court Decision 2023Du57142 makes the importance of regulatory due diligence even clearer.
The transferee acquired the business activities being conducted in both the main building and the unauthorized building.
However, the succession filing was made on the basis of the business conducted in the main building.
The Supreme Court held that if the transferee intended to continue operating legally in the unauthorized building as well, the transferee should have disclosed that the relevant business activities were also being transferred and demonstrated that the additional area satisfied the legal requirements for food manufacturing and processing.
The necessary succession and change filings should then have been completed.
The legal effect of the government’s acceptance of the succession filing was limited to establishing the transferee’s status to operate in the premises covered by the filing.
It did not legalize the use of the unauthorized building.
From the buyer’s perspective, this case should be understood as follows:
Not every space actually used by the previous operator is automatically a legally recognized business premise.
The following should align:
the space described in the transaction,
the space actually being used,
the premises reflected in the administrative records,
and the space that can legally be used for the business.
When these do not match, regulatory due diligence becomes essential.
Regulatory Due Diligence Means Matching the Documents With the Actual Site
“Regulatory due diligence” is not one standardized statutory procedure that applies identically to every industry.
In this article, the term refers to the process of comparing the existing administrative records with the actual business operation in order to determine:
whether the business can continue to operate in its current condition after the acquisition.
Reviewing a single permit or business report is only the beginning.
In practice, four areas should be compared.
① Administrative Records and Actual Business Space
What premises are currently covered by the permit, registration, or business report?
What spaces are actually being used?
② Building Compliance and Right to Use the Premises
Can the location legally be used for the intended business?
Can the buyer legally secure the right to use it?
③ Facilities and Requirements for the New Operator
Do the existing facilities meet the current statutory requirements?
Does the incoming operator need additional training, insurance, licenses, or qualifications?
④ Changes and Administrative History
Did the previous operator alter the premises or facilities?
Were the required change filings completed?
Has the business already been subject to inspections, corrective orders, or administrative sanctions?
Regulatory due diligence means connecting these four areas and confirming that they are consistent with one another.
First, Compare the Business Permit or Report With the Actual Premises
When reviewing an operating permit, business report, or registration certificate, do not look only at the operator’s name.
You should also check the scope of the premises covered by the administrative record.
Suppose you are acquiring a restaurant.
The business report covers only one unit on the first floor.
But during your site visit, you discover that the restaurant also uses an adjoining unit as dining space.
The basement is being used to store ingredients.
A separate space behind the building contains refrigerators and cooking equipment.
Tables are also placed on a terrace for customers.
The key question is straightforward:
“Are all of the spaces actually used for the business included in the current administrative records?”
If not, the discrepancy should not simply be ignored.
If the address, floor area, or other reportable matters have changed, you need to determine whether the legally required change procedures were completed.
That was precisely the issue in Supreme Court Decision 2023Du57142.
The actual business space did not match the premises recognized in the administrative records.
Second, Compare the Reported Floor Area With the Area Actually Being Used
Business premises often change over time.
A storage area is expanded.
A wall is removed to combine two units.
An additional workroom is created.
A separate room is added.
The kitchen is relocated.
The important issue is not simply whether the physical layout changed.
The key question is:
Were the legally required administrative procedures completed for the change?
In Supreme Court Decision 2023Du57142, the originally permitted floor area was 587.4㎡, while the business was actually using 748.8㎡.
Therefore, before acquiring a business, you should compare:
the reported floor area with the area actually being used for business operations.
If they are different, the first question is:
“Why are they different?”
But that is not enough.
You should also ask:
“Was the required change filing or other administrative procedure completed?”
An explanation such as:
“we have always used it this way”
does not replace the necessary administrative records.
Third, Check the Building Register
The existence of a business permit or report does not mean that all building-related issues have already been resolved.
You also need to consider the legally registered use of the building itself.
In Supreme Court Decision 2019Du38830, March 26, 2020, the Court emphasized the importance of having lawful rights to use a building that can legally accommodate the relevant business, together with compliance with statutory facility requirements.
The case involved the operation of a restaurant in a detached residential building without completing the necessary change-of-use procedure.
Therefore, rather than assuming:
“A restaurant is operating here now, so the building must be legally usable as a restaurant.”
you should verify the building records directly.
The building register is one of the first documents to review.
Building registers can be obtained or inspected through Korean government services such as Government24.
However, one distinction is important.
A compatible building use shown in the building register does not, by itself, prove that every regulatory requirement for the business has been satisfied.
The building register is an important first-level document.
You still need to review:
the actual business space,
industry-specific facility requirements,
the buyer’s right to use the premises,
and any other regulatory restrictions that may apply.
Fourth, Confirm That the Buyer Will Actually Have the Right to Use the Premises
Even if the building is suitable for the intended business, another issue remains.
Can the buyer legally use the premises?
Acquiring the equipment and paying goodwill are not the same as obtaining the legal right to occupy and use the property.
Korean Supreme Court decisions have also treated lawful rights to use the relevant building as an important condition in the succession process.
Therefore, two separate questions must be answered.
Can this type of business legally operate at this location?
And:
Will I have the legal right to use this location?
Both matter.
This becomes particularly important when:
a new lease must be signed with the landlord,
the premises are being used under a sublease arrangement,
or the buyer is acquiring only the business facilities and goodwill before the lease relationship has been finalized.
Buying the facilities inside a store does not automatically give the buyer the legal right to use the premises.
Fifth, Review Whether the Existing Facilities Meet Current Legal Standards
When buyers inspect business equipment, they usually evaluate it from a commercial perspective.
How old is the refrigerator?
Is the exhaust system still usable?
Will the interior need renovation?
Do the machines need to be replaced?
These are important questions.
But regulatory due diligence asks something different:
“Do the existing facilities satisfy the current statutory requirements for this type of business?”
Article 36 of the Food Sanitation Act requires food service businesses and food manufacturing or processing businesses to maintain facilities that satisfy the applicable legal standards.
Detailed requirements are provided in the Enforcement Rule of the Food Sanitation Act and its relevant annexes.
Therefore, the statement:
“The previous owner has always operated with these facilities.”
is not the end of the inquiry.
The question is:
Do the facilities satisfy the current requirements?
If additional facility work is necessary after closing, the buyer’s actual acquisition cost may be higher than originally expected.
Sixth, Identify What the Previous Operator Changed
One of the most useful questions in regulatory due diligence is:
“What is different now from the condition in which the business was originally permitted, reported, or registered?”
A business site naturally changes over time.
A wall is removed to connect another unit.
A separate storage area is added.
The kitchen is relocated.
More customer seating is installed.
A terrace begins to be used as business space.
A separate building is used for storage or work.
The important question is not simply whether something changed.
It is:
Did the required administrative procedures follow those physical changes?
So when inspecting the premises, do not ask only:
“Is the site clean?”
“Is the interior in good condition?”
Also ask:
“What has changed since the original permit, registration, or report?”
This question can significantly improve the quality of pre-acquisition due diligence.
Seventh, Review Existing Administrative Records and Notices
You should also determine whether the business has already been identified as having regulatory issues.
Ask the seller whether there are recent documents from government authorities, such as:
- inspection results
- corrective orders
- requests for supplementary measures
- notices of administrative sanctions
- change-filing documents
- pending administrative procedures
At this stage, the first question is not necessarily:
“Will the previous operator’s sanction legally transfer to me?”
That is a separate legal issue.
The more immediate question before the acquisition is:
“Are there already identified administrative problems affecting the business I am acquiring?”
Learning about these issues before the contract is finalized is very different from discovering them after the balance has been paid.
What Documents Are Actually Used in Regulatory Due Diligence?
In practice, you may need to compare at least the following materials.
1. Operating Permit, Business Report, or Registration Certificate
Check:
the current operator,
the business category,
the business address,
and other relevant registered information.
2. Building Register
Review the registered building use and basic building information.
3. Actual Business Premises
Confirm how far the business actually extends.
Check whether adjoining units, basement areas, storage rooms, terraces, extensions, or separate buildings are being used.
4. Available Plans or Site Records
Where necessary, compare the actual layout with available drawings or other records.
5. Lease Agreement or Other Evidence of the Right to Use the Premises
Confirm whether the buyer will legally obtain the right to use the location.
6. Previous Change Filings or Amended Registrations
If the floor area or major business details changed, confirm whether those changes were reflected in the administrative records.
7. Recent Inspection, Corrective, or Enforcement Documents
Check whether there are known administrative risks that may affect the acquisition.
Regulatory due diligence is not simply about reading each document separately.
It is about:
matching document to document, and then matching the documents to the actual premises.
The Result of Regulatory Due Diligence Can Be Viewed in Three Practical Categories
The following categories are not formal classifications under Korean law.
They are simply a useful way to think about an acquisition.
A. A Structure That Can Proceed to Operator Succession in Its Current Condition
The administrative records and actual premises are consistent.
The building use and right to occupy the premises are clear.
No material facility issues are identified.
The required supporting documents are available.
In this situation, moving forward with the applicable succession procedure may be relatively straightforward.
B. A Structure That Requires Certain Issues to Be Corrected First
The actual floor area differs from the records.
Spaces or facilities have been modified, but the change-filing history is unclear.
The right to use the premises, required insurance, or mandatory training has not yet been finalized.
In this situation, it is important to determine:
what needs to be corrected or supplemented first, and how the succession schedule should be aligned with the transaction schedule.
C. A Structure Where the Assumption of “Taking Over the Business As-Is” Must Be Reconsidered
The reported business premises differ substantially from the actual premises.
A legally questionable space is being used as a core part of the business.
The building use does not match the current operation.
Maintaining the existing business model may require substantial physical changes or additional administrative procedures.
In this situation, the key question is not:
“How do I fill out the succession form?”
It is:
“Can I actually continue the business model I expected to acquire at this location?”
This is where regulatory due diligence becomes part of the transaction decision itself.
Missing Regulatory Issues Can Create Costs Beyond Goodwill
When buyers evaluate goodwill and the acquisition price, they usually consider the existing operating environment.
The interior is already completed.
The kitchen is installed.
There is storage space.
There may be an additional work area.
The buyer therefore assumes:
“I should be able to start operating without significant additional investment.”
But after closing, the buyer may discover that part of the space cannot continue to be used.
The building use may need to be addressed.
Additional facility work may be required.
Unreported spaces may have to be excluded.
Administrative procedures may delay the start of operations.
In that situation, the business the buyer thought they were acquiring—
“a business ready to operate immediately in its current condition”
—may be different from the business actually acquired.
The consequences can include:
additional facility costs
reduced usable space
delayed opening
unexpected administrative procedures
These factors can directly affect how goodwill and the overall acquisition price should be evaluated.
For that reason, regulatory due diligence is not simply about reviewing legal documents.
It is a process for verifying what condition of business you are actually paying for.
Reading Supreme Court Decision 2023Du57142 From the Buyer’s Perspective
If this case is understood only as:
“A change in business floor area must be reported.”
then an important part of the decision is missed.
From the perspective of a business buyer, the case demonstrates three things.
First, not every space used by the previous operator is automatically a legally recognized business premise.
Second, acceptance of the succession filing does not automatically legalize spaces that were not included in the filing.
Third, a transferee who continues operating in an unreported condition may also become subject to corrective orders or business suspension.
So before signing the transaction, the buyer should not ask only:
“Can I succeed to the operator status?”
The better question is:
“Does the scope of the operator status I can legally succeed to match the business premises I am actually acquiring?”
That is the core of regulatory due diligence.
Before Paying Goodwill, Start With Three Things
Even before requesting professional review, a buyer can perform a basic first check.
Start with:
① The current operating permit, business report, or registration certificate
② The building register
③ The premises as they are actually being used
Then compare them.
Does the administrative address match the actual location?
Is the building use compatible with the business?
Is the actual operating area larger than the reported area?
Are additional storage areas or adjoining units being used?
Are extensions or separate buildings part of the operation?
If these three sources align, it is easier to move to the next stage.
If they do not, the first question should be:
“Why are they different?”
Clear Warning Signs That Require Further Review Before Closing
If any of the following situations exist, simply asking:
“Can the succession filing be submitted?”
is not enough.
① The reported address or floor area differs from the actual business premises
The actual operating area and change procedures should be reviewed.
② Adjoining units, separate storage areas, terraces, extensions, or separate buildings are being used
You should confirm whether those areas are legally included in the business premises.
③ The seller says, “The previous owner always used it this way,” but cannot provide change-filing records
Administrative records should be reviewed instead of relying on verbal explanations.
④ It is unclear whether the building’s registered use matches the current business
The legal suitability of the building should be checked.
⑤ The lease or other right to use the premises has not yet been finalized
The occupancy structure and succession schedule should be coordinated.
⑥ It is unclear whether the current facilities satisfy statutory standards
You should determine whether additional facility costs may arise after the acquisition.
⑦ There are corrective orders, inspection records, supplementary requests, or administrative sanctions
The existing issues and required follow-up measures should be identified first.
When these warning signs appear, the key question becomes:
“Can I acquire this business and continue operating it in its current condition?”
That question should be answered before finalizing goodwill and the remaining purchase price.
Not Every Business Acquisition Requires Professional Due Diligence
There are several things you can check yourself.
Request the current permit, business report, or registration certificate.
Review the building register.
Inspect the premises.
Ask the seller for previous change-filing documents and recent records from the relevant government authority.
If the documents match the actual premises, and no significant issues are identified regarding the right to use the site or the facilities, you can proceed with the applicable succession procedure.
However, if:
the administrative records do not match the actual site,
the building use is unclear,
additional spaces are being used,
the change history cannot be verified,
or there are existing corrective or supplementary notices,
the matter is no longer simply about submitting one succession form.
The review should connect:
current administrative status → actual premises → building and right of use → facilities → required changes or administrative procedures
as one transaction structure.
When Acquiring a Business, You Need to Review Both “Who You Are Buying From” and “What You Are Actually Buying”
The order of review matters.
First:
Can I legally acquire the business from this person?
Then:
Can I take over the premises in their current condition and continue operating the business?
And if the due diligence identifies issues:
How should those risks be reflected in the transaction conditions and acquisition schedule?
Before acquiring a regulated business in Korea, at minimum compare:
Current permit or registration / Building register / Actual business premises
If these are consistent and there are no significant issues regarding the building, right of use, or facilities, you can move to the next administrative step.
But if the actual premises differ from the administrative records, or the building use, facility standards, right of use, or change history is unclear, the first priority should be determining whether the business can actually be taken over in its current condition before the purchase price and remaining balance are fully paid.
At ETHOS, we compare the existing administrative documents, building records, and actual operating conditions to review:
① discrepancies between the administrative records and actual premises,
② building use and the right to use the premises,
③ facility and modification issues, and
④ administrative procedures that should be completed before succession.
If the matter has already developed into a civil dispute concerning contract validity, repayment of the purchase price, or damages, those issues should be distinguished from the administrative process and may require review by a Korean attorney.
Based on the existing permit or registration, building records, and actual use of the premises, you can request a complimentary preliminary review to determine whether the business can be succeeded to in its current condition and what should be corrected or addressed before closing.
